4. Press firmly for 10 - 12 seconds. It takes a minimum of 10 seconds to fuse interfacing to any fabric. The heavier the fabric, the more seconds it takes, so adjust your timing accordingly.
5. Do not glide iron back and forth. Use a lift and press motion.
6. Turn pieces over and repeat process on the right side of fabric to achieve a smooth secure bond.
7. Be patient. Always allow fused pieces to cool completely before handling them.
8. If the iron is too hot, bubbling may occur. Adjust the iron to a lower temperature and do another test increasing the fusing time.
9. If your fashion fabric is too light or sheer for the interfacing the coating may show through on the right side of the fabric. In this case use a lighter weight fusible or try using a sew-in interfacing.

FINALLY...
take notes while you test and keep a record of the time and temperature which produced the best results with your fabric and interfacing. When you are fusing the interfacing to your garment pieces, refer to your notes and follow the time and temperature you found most successful. When fusing large areas, slightly over lap your iron placement to insure that the entire area has been fused. Be sure to keep the notes with the interfacing remnants for future sewing projects and you will soon develop favorites suited to the fabrics and items you sew most."
